Baader Hyperion Zoom Eyepiece and Barlow

No, the eyepiece features a parfocal design, which means the focus remains consistent as you zoom through the focal lengths. You may only need a very slight adjustment depending on your personal eyesight.

Yes, it is highly versatile. It comes with both 1.25-inch and 2-inch barrel adapters, making it compatible with the vast majority of standard telescopes and spotting scopes on the market.

The 2.25X Barlow lens effectively multiplies the magnification range of the eyepiece. When attached, the standard 8-24mm focal length range is extended, allowing you to achieve higher magnification for detailed planetary or lunar observation.

Absolutely. The flat-field optical design provides sharp, high-contrast images across the entire field of view, which is excellent for spotting scopes and terrestrial observation where edge-to-edge clarity is essential.

The Phantom Multi-Coating is designed to maximize light transmission and minimize internal reflections. This results in brighter, higher-contrast images, which is particularly helpful when observing faint celestial objects.

At 10.2 ounces, this unit is heavier than a typical single-focal length eyepiece because it contains complex zoom optics. Ensure your telescope's focuser is balanced to handle the weight, though it is still compact enough for most setups.
